Abstract
Since the ancient times, onion and honey is used to cure several diseases, mostly because of their antibacterial properties. Onion-honey cough cure is a remedy prepared with onion juice and honey and it is used to alleviate cough and the symptoms of cold. Although this remedy is used a lot in Turkey, it is not certain whether the onion-honey cough cure is more effective against the bacteria compared to only onion juice or only honey. Because of that, the aim of this experiment was to investigate the antibacterial effects of onion juice, honey and onion-honey cough cure for their different concentrations. Since the resistivity of gram-positive and gram-negative bacteria towards antibacterial agents are different, antibacterial effects of onion-honey cough cure, onion juice and honey investigated on a gram-negative bacterium, E. coli, and a gram-positive bacterium, S. aureus separately. Microtiter plates were filled with different concentrations of onion juice, honey and onionhoney cough cure and they were inoculated with S. aureus and E. coli with the help of Micro Dilution Test. It was found that since onion-honey cough cure has the same antibacterial property with the flower honey for E. coli (reproduction of E. coli both starts at a concentration of 50%) and it has the same antibacterial property with onion juice for S. aureus (reproduction of S. aureus both starts at a concentration of 6.25%), it cannot be accepted that onion-honey cough cure has a greater antibacterial effect compared to onion juice and flower honey. Besides that, it was seen that S. aureus was more susceptible to onion juice, honey and onionhoney cough cure compared to E. coli when the concentration they start to reproduce is compared. On the other hand, difference between the antibacterial effects of onion juice, honey and onion-honey cough cure and the difference between the susceptibility of E. coli and S. aureus cannot be proven statistically since the p values of Chi-square test was always bigger than 0.05. To sum up, results of the experiment showed that onion juice, honey and onion-honey cough cure have all antibacterial properties on the gram positive bacteria, S. aureus, and gram negative bacteria, E. coli but the difference between their effectiveness cannot be proved with Chi-square test due to unbalanced distribution of the data.
